Felling

– Methods
– Hand felling: Utilizes an axe, saw, or chainsaw for tree felling, followed by limbing and bucking.
– Feller buncher: Motorized vehicle with an attachment that rapidly cuts and gathers trees during felling.
– Types of cut: Includes undercut, notch cut, back cut, felling cut, and Tongue and Groove cut.
– Boom-corridor experiment: Conducted to study continuous felling of trees for increased harvester productivity.
– Gallery: Shows timber logs cut for logging, a piece of trunk, urban felling in Russia and Australia, and a video of tree felling.

– Hand Felling
– Uses axe, saw, or chainsaw for tree felling.
– Followed by limbing and bucking in traditional applications.
– In modern logging, felling is followed by limbing and skidding.

– Feller Buncher
– Motorized vehicle with attachment for cutting and gathering trees.
– In cut-to-length logging, harvester performs felling, delimbing, and bucking.
– Recommended methods for maximizing wood recovery during harvesting.
– Suggested trend of making deeper cuts and smaller openness in undercuts.

– Types of Cut
– Undercut and notch cut guide the tree’s fall direction.
– Back cut or felling cut is made opposite the undercut to fell the tree.
– Tongue and Groove cut uses the tree as its guide for precise falling.

– Boom-corridor Experiment
– Study on continuous felling of trees in boom-corridors.
– Use of felling heads to increase efficiency and fall time.

– Gallery
– Shows timber logs cut for logging.
– Displays a piece of trunk.
– Depicts urban felling in Russia and Australia.
– Video of tree felling, limbing, bucking, and moving.
